The second law of thermodynamics states that not all of the energy is used because some of the energy is lost in the form of heat. The lost heat energy is an unusable form of energy, and it causes an increase in the entropy of the universe. Thus, no energy transfer process is efficient due to the loss of energy.
Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products. ... The enzyme's active site binds to the substrate.
The answer is A.
If the bicipe muscle contracts it will bring the forearm up because the insertion of this muscle is in the forearm.
One of the functions of this muscle is flexing the elbow, which would result in the action i already mentioned.
It couldn't be B, because that would be the work of another muscle, the triceps.
1. tiny sacs within the lungs which increase the surface available for gas exchange = alveoli
2. a digestive enzyme that breaks down starches and glycogen into sugars = amylase
3. the two thin-walled chambers that receive blood into the heart from the veins = atria
4. the two tubes into which the trachea divide to go into each lung
= primary bronchi
5. a tiny vessel through which diffusion takes place between the blood and the body tissues
= capillary
6. a mass of nerve tissue not part of the brain = ganglion
